I'm currently painting my dining room and decided to replace all the electrical outlets. However, I found one outlet with a surprising setup—it has 6 wires attached to it! There are 3 hot wires and 3 neutral wires. On the hot side, there are two wires connected to one lug and one to the other, and it's the same for the neutral side. All my other outlets just have one hot and one neutral. I'm puzzled about why there are so many wires here. Any ideas?

It sounds like you've got a GFCI setup going on, but if it’s not a GFCI, you might want to consider replacing that outlet with pigtails. It can help simplify things and is generally a safer way to connect multiple wires without overloading the outlet.
You should disconnect all those wires and use a multimeter to figure out which ones are the main hot and neutral feeds. Leave those connected, and then try connecting the other pairs one at a time to see which outlets or lights they power. It could be that the previous owner overloaded a circuit, and it’s good to know exactly where your power is coming from.
It sounds like the previous owner might have been trying to tap into that outlet to extend the power elsewhere without using proper pigtails. I’d recommend removing those wires and properly wiring them together with wire nuts or Wago connectors, ensuring only two wires go to each screw on the outlet.
Is that wrong? I thought that was a standard way to use an outlet as a junction box. I've seen it done a lot, but I'm no electrician. And yeah, getting into those boxes can really be a pain!
